  • Automated gain control in rail flaw detection
    Patent number: 4205553
    Abstract: Automated gain control in rail flaw detection which includes attenuation of echoes from rails pulsed with a burst of sonic energy, comparing said attenuated signals over discrete intervals, and reducing or increasing said attenuation in response thereto to develop a uniform signal from which an evaluation of flaw indicating echoes can be obtained.
    Type: Grant
    Filed: February 21, 1979
    Date of Patent: June 3, 1980
    Assignee: The United States of America as represented by the Secretary of the Department of Transporation
    Inventors: Robert P. Rudis, Harry L. Ceccon
  • Automatic base gate positioning circuit
    Patent number: 4137776
    Abstract: An automatic base gate positioning circuit for use in rail flaw detection is disclosed which includes the generation of a string of uniformly spaced pulses corresponding to known rail depth, correlating said pulses with sonic echoes averaging and storing the correlated signals and developing a signal representing the rail depth for comparison with an echo from the rail base.
